(Source : Energy Saving Trust)How do I know if I need to insulate my loft?
Tell tale signs include:
- Cold house (I know it's pretty obvious isn't it?)
- House cools down rapidly as soon as heating is turned off
- Older houses are more...
I have had so many people asking me about home energy monitors that I thought I might as well just get something down in text!
For a start let me answer some common questions :
- What are Wireless Electricty Monitors?
- How do Wireless Elecrtcity Monitors Work?
- What are the benefits?
- What are the alternatives?
- Will they save me money?
- Are they easy to fit?
The Arctic is losing it's old, thick ice faster than has been seen in previous years despite cold weather across the Northern Hemisphere. The warm 2007 summer saw the smallest area of ice ever recorded in the Arctic and scientists fear that the trend will continue this year.
Reduced areas of ice have a compounding effect on global warming as white ice reflects warmth back into the atmosphere, whereas, the dark ocean absorbs heat.
March is usually the time that the Arctic ice covers the largest area. In 2008 the area covered will be slightly larger than than it was in 2007, however this masks an underlying trend that shows the amount...
The Bali talks were finalised back in December 2007 with a last minute agreement following a U-turn by the United States, which had been holding out for firmer commitments from developing countries.
Precise targets were not set, however the so called ‘Bali roadmap’ initiates a two year process of negotiation to develop and agree a new set of emissions targets to replace those in the Kyoto Protocol.
The EU had pressed for a commitment that industrialised nations should commit to cuts of 25-40% by 2020, but this was opposed by a bloc containing the US, Canada and Japan.
The final text does not mention specific emissions...
The Intergovernmental Panel on Climate Change (IPCC) has released it’s Synthesis Report – the final part of the IPCC Fourth Assessment Report : Climate Change 2007.
The Synthesis Report, which is the end-product of the most detailed and thorough assessment of global climate change ever undertaken, states that urgent action must be taken to reduce greenhouse gas emissions otherwise climate change will intensify and have dramatic implications for both the natural world and human society.
The report is a product of intense week long discussions in Valencia, Spain, and provides a definitive conclusion to the climate change debate....
The BBC have reported this week of the United Nations Secretary General Ban Ki-moon’s alarm at the pace of climate change after his two-day fact-finding trip to southern Chile.
Mr Ban, who has vowed to make the fight against global warming a key issue during his tenure at the UN, went to Antarctica on Friday where he heard from scientists how rising temperatures have caused huge ice shelves to collapse into the sea.
He also saw the Grey glacier, the front face of which is covered in cracks, which experts believe are due to the warmer weather conditions.
Mr Ban is gathering information to take to a major UN conference on
Revisions to the draft Climate Change Bill, originally produced by the Government in March of this year (see earlier ecofreak news item "Climate Change - UK Leads The Way"), were set out yesterday by Environment Secretary, Hilary Benn.
The original draft Bill set out clear legally binding targets for reducing carbon dioxide emissions in the UK by at least 60 per cent by 2050, and from 26 to 32 per cent by 2020. This is to be based on a new system of “carbon budgets” set at least 15 years ahead. It also proposed the creation of a new independent, expert Committee on Climate Change to advise on the best way to achieve these...
Planning approval means the £28 million project, which has been developed by the South West of England Regional Development Agency (RDA), has cleared the last major regulatory hurdle. Funding for the project has already been approved by the RDA.
The project, named Wave Hub, is a world first and will include an onshore substation connected to electrical equipment on the seabed about 16 kilometres (10 miles) offshore via a sub-sea cable.
Companies developing wave energy technology will be able to plug into Wave Hub to test their wave energy devices on a scale never seen anywhere before. Four companies have already been chosen to...
